DENVER - 9Wants to Know has learned a Colorado man is in federal custody after plotting to kill President Barack Obama and kill children on Halloween night in Westminster.

Sources tell 9Wants to Know Mitchell Kusick's plan involved stealing a family member's shotgun and using it to shoot children on Halloween and assassinate the president in Colorado.

Officials do not know when he wanted to kill the president.

The restraining order filed in Jefferson county court says Kusick "stole a shotgun from his aunt's house, hid the weapon, attempted to purchase ammunition for the gun" and then told his therapist about his plan.

The court paperwork goes on to say Kusick confessed to law enforcement about "his intent to shoot children at Standley Lake High School during a trick-or-treat event." It also says Kusick talked to law enforcement while he was admitted to Lutheran Hospital and figured he would "engage police in a gun battle" after the shooting at the school.

He told authorities he wanted to go down in infamy for being a mass murderer.

Investigators say Kusick told them of his fascination with the Columbine High School massacre, the Virginia Tech shootings and Aurora theater shooting suspect James Holmes.

"I share an understanding of [Holmes'] situation," he said.

After admitting to a fascination with bombs, prosecutors say Kusick told them, "some people just want to watch the world burn down, and I'm one of them."

When it came to killing the president, he claimed it wasn't really about Obama. Kusick, who is registered unaffiliated, thought Obama had done a good job.

Voting records show his mail in ballot arrived at the polling place on the very day President Obama spoke to 16,000 people in Denver City Park.

Kusick told a Secret Service agent investigating this case that he'd been planning on killing people for five to six years.

Court documents say he had seen a counselor for eight to nine years.

The paperwork says he is charged with"interference for threatening to shoot children in Jeffco Schools."

Jefferson County School District filed a restraining order against Kusick Nov. 9.

Jeffco Public Schools released the following statement in regards to Kusick:

Working with law enforcement, Jeffco Schools learned of a man who was allegedly threatening students at Standley Lake High School's Trick or Treat Street event. Police acted quickly to take the man into custody before the event. At no time were children attending the event in any danger from the suspect because he was already in police custody. We appreciate the swift response from law enforcement and Jeffco district security which helped keep our students safe.
